我想从嵌套表中获取表。

创建表类型:

CREATE OR REPLACE TYPE Name_list_t AS TABLE OF VARCHAR2(50)

更改我的表添加列嵌套表:

ALTER TABLE MOVIES ADD Movi_name_list Name_list_t NESTED TABLE Movi_name_list STORE AS Movi_name_list

将表添加到嵌套表:

Declare
extractNames Name_list_t;
Begin
(...) some code...
update movies set movi_name_list=extractNames where movi_id=id_movie;
End;

插入表格效果很好。最后,我想从嵌套表中获取表,但我不知道如何。我尝试了两种方法但没有成功:

select movi_name_list into extractNames from movies where movi_id=1; 
extractNames := select movi_name_list from movies;

谢谢您的帮助。

@Egor Skriptunoff工作中选择!

解决方案:

select column_value bulk collect into extractNames from table(select movi_name_list from movies where movi_id=1)

我猜我的选择不正确。
